nCine::RHI::LegacyGL::LegacyGlTexture::Page struct
#include <nCine/Graphics/RHI/LegacyGL/LegacyGlTexture.h>

One GL-addressable piece of the texture.

A texture no larger than MaxPageDimension on either axis has exactly one page covering it whole, which is the case for practically all content; bigger images are tiled by pages (see the class documentation).
